Particle image velocimetry (PIV) uncertainty quantification using moment of correlation (MC) plane [PDF]
Measurement Science and Technology, 2018 We present a new uncertainty estimation method for Particle Image Velocimetry (PIV), that uses the correlation plane as a model for the probability density function (PDF) of displacements and calculates the second order moment of the correlation (MC).

Particle Image Velocimetry Algorithm Based on Spike Camera Adaptive Integration [PDF]
SensorsIn particle image velocimetry (PIV), overexposure is particularly common in regions with high illumination. In particular, strong scattering or background reflection at the liquid–gas interface will make the overexposure phenomenon more obvious ...

Grid turbulence studied by Particle Image Velocimetry [PDF]
EPJ Web of Conferences, 2022 We studied the grid-generated turbulence by using Particle Image Velocimetry (PIV) technique. We test on this already well studied flow the new ways of analyzing spatially resolved PIV data, such as the spatial spectra and structure functions. We compare
